Known Issues:
[r26861] - Autocomplete/ select box values are not being correctly populated in Linux. As a work around you can use the up/down arrow keys to view the current selection.
[r26600] - Task bar icon in Windows does not update/ display correctly.

I noticed that in previous builds when I clicked in the address bar all of the text was selected and so you could just start typing. In this build (running in Ubuntu 9.10 if that makes a difference) clicking in the address bar doesn't select the existing text. Minor, but it is kind of annoying.
